SAN FRANCISCO, CA--(Marketwire - July 07, 2008) - Thomas Weisel
Partners Group, Inc. (NASDAQ: TWPG) (TSX: TWP) announces that its
Chief Financial Officer search is completed and that Shaugn Stanley,
the interim Chief Financial Officer, will be appointed Chief
Financial Officer and will become a member of the Executive
Committee. Supporting Mr. Stanley in the finance department, Keith
Harris, the prior Chief Financial Officer of Westwind Partners, will
become Chief Operating Officer of TWP Canada and the firm's
Treasurer, and Ryan Stroub, previously the Head of Finance, will
become the Chief Accounting Officer.

"I am delighted to accept the position as Chief Financial Officer.
The firm continues to maintain a strong balance sheet with
substantial liquidity. As of May 31, 2008, the available cash is
approximately $130 million, an increase of $19.5 million from $110.5
million reported at the end of the first quarter. As of the end of
the second quarter of 2008, these amounts have not changed materially
from May 31, 2008. The firm's excess regulatory capital as reported
in its most recent regulatory filings is $70 million, up
substantially from $43 million in excess regulatory capital as of the
end of the first quarter. In addition, during the second quarter, we
retired a $2.8 million secured financing due in December 2008. Our
only remaining debt was issued in conjunction with our initial public
offering in exchange for equity interests and is not due until 2011.
Finally, having completed our previously announced headcount
reductions and other related expense reductions, we believe we are
well positioned to benefit from a return to a more normal market
environment," said Mr. Stanley.
